Commelina tuberosa. Bot. mag. 1695.
Root perennial, composed of a fascicle of long
subcylindrical tubers. Stems several from the same
root, erect, smooth, slightly furrowed, not much
branched. Leaves sessile, sheathing the stem, oblongly
lanceolate, taper-pointed, undulate, smooth, but fringed
at the base, 7-nerved. Sheaths fringed. Peduneles
terminal and axillary, densely pubescent, scarcely as
long as the leaf. Involucre cordate, taper-pointed,
pubescent, doubled inwards so as to cover the flowers
before they expand. Raceme many-flowered, inclosed
in the involucre. Pedicles smooth, bent forward before
the flower expands, erect when expanded, afterwards
